On April 29, Microsoftofficials told the folks at Bloomberg that Azure had crossed the $1 billion threshhold. The Softies also said Azure subscriptions have risen 48 percent in the past six months, Bloomberg reported.

Microsoft officials said recently that Office 365 also is poised to become one of its $1 billion businesses. I'd expect that to happen in the next few months, as Microsoft completes its current fiscal year and continues to upgrade more customers to the latest version of its Office 365 business and consumer subscription services.
